To all 'whom z'tmag/ concern:

Be it known that I, HARRY EHLIG,a citi- Zen of the United States, and a resident of Pearl River, inthe county of Rockland and 5 Statek of New York, have invented-certain new and useful Improvements i in Folding and Slitting Machines, of*4 which the following is a specification, reference being made to the accompanying drawings, forminfr a part thereof.

folding and slitting printed sheets asthey are delivered from a printing-presser other like machine, and therobjects of my inventiony are, amongother things, to provide a lmachine of that type with means by which the rotary cutting bars used-for longitudinally slitting the sheets as they areffolded may be readily removed from thev machine, while `the mechanism for delivering such folded `and slitted sheets may be y easily swung from operative position to afford ac' cess to the cutting bars whereby they op-' erator may detach same from 'the machine without shifting or disturbing any part of their actuating devices. Furthermore my improved machine also enables the different parts with their actuating devices to" be readily reassembled in operative position. A further object is 'to provide simpleand v highly efficient mechanismsfor handling the successive sheets as they. are forwarded to my improved folding and slitting machine in which there are aminimum of Operative parts so that dependability,accuracy of reg,- ister,l mechanical balance andxhigh .speed may be attained. These and othery objects 1 will be hereinafter fully set forth and particularly pointed out in the appended claims.

The accompanying drawingsiillustrate a preferred embodimentof my'invention in which-V f .i

nimilar numerals refer to similar throughointv the several figures. i Referring to the drawings, thesideframes parts 10 and 11 support :the yvariousxparts embodied in .my improved machine; from kthe top of these side frames.extendtransversely two cooperating foldingrollers 12 and 13 mountedon shafts 14C and 15 which are journallediin suitable brackets 16 and 17 located on theltop of the side-frames 10and 11 respectively. Below the folding.- rollers 12 and 13 are the coacting cutting bars 18 and 19 as shown in Figs. y2fandx6. Thesek fold`- ing rollers 12 and13 and cutting bars 18 and 19 yare rotated in unison by the follow.- ing mechanism best shown in Figs. 1 and 2. Power Vis derived from any suitable source to rotate the gear wheel 20 which engages with the gear 21 carried by the shaft l5 outside lthe frame 10 (Fig. 1); the shaft 15 also .carries the gear 23 which enmeshes withy the gear 22 mounted on the shaft 14. .The cutting bars 18 and 19 have coacting driving gears .2dand 25 respectively, the gear 25 being driven by the idler,` gear 26 secured to the stub-shaft .27 journalled in the `bracket 28 in the side-frame 10. The

left ends of the shafts 31 and 32 (Fig. 1) carry the coacting gears 33 and 34, the gear 34 being driven by the idler ygears 35 and 36, gear 36 enmeshing with the idler gear 26, all as shown in Fig. 2.

The tvvo ends ofthe shaft 31'are journalled in slotted brackets 37 and 38 angularly secured to the side-frames 1() and 11 respectively so that the upper delivery roller 29 with its shaft 31 may be easily lifted out of the slotted brackets 37 and 38,

. and the teeth of tliejgears and 34 may also be readily disengaged to ipermit the removal of the roller29.

Referringto Figs. 3 and k4, the riglit-ends of the cutting bars 18 and 19 are journalled in the bearings 39 -and 40 respectively formed in the Asupporting block 41 which lis slidingly mounted on the L-shaped `bracket 42 secured to the Vside-frame 11 by the 'screws 43. The top surface of the block 41 has the channel 44 formed vtherein which engages with and slides alongthe bracket 42 and is held in its full line loperative position when the screvi7 :bolt 45 passes through the hole 46 -of the bracket 42fand engages with the `screW-threaded bore 47 cut linfthe block 41 as shown in Figs. 1,3 and 5. lhen the bolt 45 is removed,the block 41-may be readily shifted 4to the -rightzin Figs. 1 and-3 as indicated by the dotted lines, which causes the right ends'of'the cutting-bars 1S and 19 to slip from their respective bearings 39 and 40. Then such cutting bars may be removed fromlthe machine by shifting same to the right in Fig. 1,'thereby disen aging'thegear-25 from the idlergear 26.

leferring to Figs. 1,6=and 9, the disk48 having the annular groove 49 is mounted on the cutting 'ba-r 18 while the coactingcutting bar 19 carries the disk 50 having the circular `cutting edge 51 to cooperate with the groove 49 to slitthe folded sheets fed between them as shown in Figs. 6 `and 9.

may be carried by these bars as shown in Fig. 1, and they may be shifted transversely on the bars 1S and 19 to cut the sheets into different vsisces as required.

I have provided a removable delivery mechanism with associated elementswhich may be swung downwardly whenit `is desired to remove the cutting bars, the upper delivery roller 29 being arranged so Aas to be raised out of the slotted brackets 37 and 38 as heretofore set forth. In the embodiment shown more particularly in Figs. 1, 2, 5 and 6, the lower deliveryroller 30 with its shaft 32 is journalled in the fiee ends of the rock-arms 52 and rigidly mounted.

on the cross shaft'54 journalled in the dependingbrackets 55 and 56 secured to the under sides ofthe side-frames 10 4and 11 respectively. Also carried by the crosssh'aft 54 and extendingtransversely of the machine between the side frames 1() and 11 is the curved delivery Iplate y57 secured to arms 5S (only one shown in Fig. 6) rigidly affixed to the shaft The right end of the shaft 54 extends through the bracket 56 outside the side-frame 11, `and ha'smounted thereon the latch arm 59 having the handle 60 carrying the latch-pin 61 which is normally pressed forwardly by the coil spring (52m-.engage the hole 68 formed in the sidef frame 11 as shown in Fig. 7, When the latch-pin 61 is withdrawn from the hole 623 by thef'handle t60, and the arm 59 is depressed as shown by dotted flincs' in Fig. 6, the lower delivery roller 30 andalso thedelivery .plate 57 are swungailownwardly into the respective dotted line positions shown in Fig. 7, vgiving freeaccess to the operator to remove the cutting fbars y18 and 19 after the upper delivery-roller 29 has been raised out of the slotted brackets 3T and-38. These movable :parts can be restored totheir full line positions when the latch-arm59 is again raised so as to Ibriiigthe latch-pin 61 into engagement with the hole 623 to hold their delivery devices in operative relationship with theslitting devices and upper delivery roller 29. f

Referring to Fig. 6, the folding blade 64 is mounted on the end ofthe rock arm 65 secured to the rock-shaft 66 l.journalled in l ing rollers 12 and 113 by anyA convenient Two vor more seits ot suchslitting devices means; in the-embodiment shown infF 6 the delivery tapes T1 passing around the tape roller T2 perform this preliminary foiwarding of the sheet into the fullfline position shown preparatory to folding and slitting with subsequent delivery from between the delivery rollers 29 ande() as shown by the dotted line `in tlie'lower part of Fig.

lVhen it becomes necessary or desirable to remove the cutting bars 18 and 19 from the machine, the operator pulls the handle v60 outwardly to disengage the latch-pin 61 from the hole 653 and then depresses the latch-arm 59 which rotates the shaft 54 in` va clock-wise fdirection as shown` in Fig. 6.

roller 30 and the delivery plate 5T downwardly to the left in Fig. 6 tothe dotted line positions there shown, and'tlien the upper delivery roller is lifted out of the slotted brackets 3T and 88, or this delivery kmachine.

roller 29 may b e first removed before the operator depresses the latch-arm 59 to lower the delivery roller 30 and plate 57. The bolt 45 is then unscrewed from the hole 46 and bore 47 which enables the operator to pull back the block 41 on the bracket 42 to the right to the dotted line positions shown in Figs. 1 and 3, and the right ends of the cutting bars 18 and 19 thereupon slip from their respective bearings 39 and 40; the operator then moves the cutting bars 18 and 19 to the right in Fig. 1 thereby disengaging their actuating gears 24 and 25 from the gear 26; the cutting bars 18 and\19 may now be lifted forwardly and out of the To reassemble these parts in operative position the reverse of these several steps is followed, the latch-arm 59 and pin 61 bringing the roller 31 and plate 57 back to the full line position shown in Fig. 6.

The invention is not to be limited to the particular constructions shown, nor to any particular constructions by which it may be carried into effect, as many changes and alterations may be made without departing from the principles' of the invention, and without sacrificing its chief advantages.
